Webster, who worked at the corner shop in Penrhyn Road, said: “When they changed the system to Unified, it created a new job for HMRC, so I was technically employed by Kingston twice.

“For some reason when it created the second job, my tax rate was at something stupid like 80 per cent so my pay cheque, which was supposed to be £400, came through at £25.

“It’s sorted now, but it took a significant amount of time.”

Others have found that confusion with how the system worked was the cause of original delays in payment.

Third year business and management student Aditya Tandon said: “I am on a couple of jobs with the university in different departments. Initially, student-staff weren’t given enough briefing on how to access Unified and to claim hours.

“It was more like a guessing game for everyone.”

Students are now receiving the pay they are owed and the University claims that the issues have been resolved.

A Kingston University spokesperson said: “There has been a comprehensive introduction programme for staff – including developing a network of superusers and providing training materials, quick guides and workshops.

“Despite initial challenges, the core functions of Unified – paying staff, receiving income and paying bills – are working well.”
